Background The main objective of this study was to resolve fascia iliaca compartment block controversies by putting the currently available evidences applied for knee, femoral shaft, and hip bone injury or related to surgery. Methods The databases PubMed, Cochrane Review, and Google Scholar were searched without regard to language or publication type for fascia iliaca compartment block before December 2020. After eligibility sorting and duplicate removal, a total of 26,609 articles were identified, with 21 of them being included for review. Discussion In the emergency department, fascia iliaca compartment block (FICB) has now become the standard of practice. Various evidence suggested that 20–40 ml of local anesthetic was required for an effective block in adult patients. Conclusion For the knee, femoral bone, and hip region surgery, the fascia iliaca compartment block (FICB) provided better anesthesia quality, reduced systemic morphine consumption, and had fewer complications than epidural anesthesia. Anesthetists and surgical department staff should promote the FICB's benefits by emphasizing its superiority in pain management.

Introduction: Unexpected cardiac arrest during the intraoperative period contributes to higher morbidity and mortality. All patients undergoing surgery and anesthesia have a risk of having a cardiorespiratory event perioperatively. Presentation of case: A 70 years old female (Gravida 7, Para 7) patient having an elective transvaginal hysterectomy under spinal anesthesia. After 1 hour and 25 minute, the patient had sudden intraoperative cardiac arrest noted with loss of carotid pulse, undetectable blood pressure, and chaotic irregular deflection with decrement of amplitude on ECG. Immediate resuscitation was done with chest compression, endotracheal intubation, and epinephrine administration. The patient extubated in the operation room and wean after a day from vasopressor support in the intensive care unit then patient discharged safely after a week. Discussion: Intraoperative cardiac arrest is a very infrequent and unanticipated adverse event following noncardiac surgery. Urgent surgeries, lower American Society of Anesthesiologists (ASA) physical status, and trauma are major contributors to this unwanted event. 4 ''H'' and 4 ''T'' mnemonics are well-known reversible causes of cardiac arrest. Deterioration in hemodynamic status during surgery is an indicator of an upcoming cardiac arrest. Conclusion: Patients with low risk score for perioperative cardiac event might develop a sudden intraoperative cardiac arrest. Preparation for resuscitation at any time of surgery is very important in the management of sudden and unexpected cardiopulmonary arrest during surgery. Highlights
